Irish companies like Glanbia have used covert deals with the government in Luxembourg to slash their tax bills in their own country.
Documents released by an international group of newspapers including the Irish Times, show how over 300 companies reached deals with the government there.
The deals, which ARE legal, allowed companies worldwide to slash their tax bills by setting up new subsidiaries in Luxembourg with few employees - or often none at all.
Other companies used the deals to set up offices in Ireland that helped them avoid tax elsewhere.
